Material Method: 34 thyroidectomy cases(27 of total thyroidectomy, 7 of hemithyroidectomy) with use of I-IONM, between June 2016 and June 2017 were retrospectively examined. Predissection(R1, V1) and postdissection(R2, V2) EMG waveforms of the right and left sides’ vagal nerve (VN) and RLN were evaluated.
Results: There were 29 females and 5 males patients with mean age of 43.85±13.86 years. 61 nerves at risk were successfully evaluated with I-IONM. Mean R1 and R2 amplitudes of the right RLN were 280±10 µV and 270±9µV; the left RLN were 270±10µV and 260±9µV respectively. Mean V1 and V2 amplitudes of the right VN were 210±7µV and 190±7µV; the left VN were 190±5.4µV and 170±5µV respectively. Mean R1 and R2 latencies of the right RLN were 2.03±0.42mS and 2.0±0.46mS; the left RLN were 1.90 ± 0.30mS and 1.96 ± 0.33mS respectively. Mean V1 and V2 latencies of the right VN were 1.91±0.46mS and 1.82±0.52mS; the left VN were 2.01±0.34mS and 2.07±0.38mS respectively. There was no statistically significant difference between the sides in terms of electromyographic waveforms of the VN and RLN. Conclusion: The left RLN has a longer anatomical length than the right RLN but we concluded that the length of the nerve does not affect the amplitude and latency.}, number={2}, publisher={Tekirdağ Namık Kemal Üniversitesi}
